More than 42,000 visited Canada’s Outdoor Farm Show at Woodstock, just shy of the record 43,900 attendees in 2017. One of the most talked about attractions was the demonstration of a driverless machine that hooks itself up to farm implements and can be used to pull planters, a sprayer and combines. The U-shaped mechanical frame — called the Dot power platform — costs $350,000. (Bryce Douglas photo)
